ALFRED FOWLER AND GEORGE E. \VARREN, OF PAWTUCKET, RHODE ISLAND,ASSIGNORS TO THE CAMPBELL MACHINE COMPANY, OF SAME FLA CE.

SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 549,353, dated November5, 1895.

Application filed May 28, 1894. Serial No. 512,694.. (No model.)

To all whom it may concern:

Be it known that we, ALFRED B. FOWLER and GEORGE E. WARREN, both ofPawtucket, in the county of Providence and State of Rhode Island, haveinvented a new and useful Improvement in Sewing Machines, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which- Figure 1 is an elevation showing my invention asapplied to both penetrating instruments; Fig. 2, a section on line :200c of Fig. 1; Fig. 3, two viewsof the awl-holder, and Fig. 4 two viewsof the needle-holder.

Our invention relates to means for supporting and actuating the needleand awl, and one feature of our invention consists in arranging theholders for the needle and awl in a single support, another featurebeing the use of a curved rack in a curved guideway as the holder forthe needle or for the awl, or for both, thereby providing a clear space,which has heretofore been occupied by the shaft or journal of theholder.

In the drawings, which illustrate the best form of mechanism embodyingboth features of our invention, A is the needle-holder and a the needle,B the awl-holder and b the awl, and D the support for both. This supportD is shown as a feed-slide, but may, of course, be fixed to the frame ofthe machine if some other feed be provided. 0 I

The support D receives both holders A and B and confines each tomovement about its axis, and the needle a and awl b are mounted each inan ofiset on its holder in order that the points of both may move in thesame plane. One advantage of putting both holders A and B in a singlesupport D is that the offset may be reduced to the minimum, and therebybring the thrust of each as nearly direct with relation to its supportas is possible, and in addition the construction is simplified as wellas made more compact. This feature of our invention is applicable in anymachine using a needle-holder and an awlholder, and may be used with orwithout the second feature of our invention, which relates wholly togetting free space within the circular path of the needle-point, thisbeing especially desirable in hooked-needle sewingmachines, in order togive ample room for the material to be sewed and also mechanism forbringing the thread into proper relation with the hook of the needle,and this feature of our invention consists in a needle holder which is acurved rack combined with a support provided with a curved guideway bywhich the rack is confined to its proper motion in the arc of a circlewithout the need of any central support.

The holders A and B are shown as actuated by the racks a and 19*, theirlevers a and b,

and suitable cams, as will be plain without further description.

What we claim as our invention is 1. In combination a curved needle; aneedle holder which is the segment of a ring; a curved awl; an awlholder which is the segment of a ring; and a casing with curved guideways for both segments; all substantially as described.

2. In combination a curved rack carrying a clamp for the shank of theneedle; a support inclosing the curved rack; curved guide waysconnecting the'curved rack and the support and confining the rack tomotion in its arc of curvature; and a toothed driver engaging with thecurved rack, substantially as described.
